VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 424,579, dated April 1, 1890.

Application filed January 10, 1890. Serial No. 336,498- (N 0 model.)

To alZZwhom it may concern.-

Be it known that 1, JOHN HENRY ROWLAND, stairbuilder, a subject of the Queen of Great Britain, residing at 152 Pelham Street, Carlton, in the British Colony of Victoria, have invented certain new and usefullmprovements in and relating to iVheels for Buggies, Oarl'iages, Lorries, and other Vehicles, of which the following is a specification.

This invention has been devised for the purpose of providing a comparatively simple and inexpensive wheel, which will be more satisfactory and reliable in use than are those of ordinary construction. Its essential features are:

First, that the hub consists of two hollow castings screwed together and fastened the one to the other by bolts passing through flanges formed on their inner ends, while the inner ends of the spokes of the wheel are adapted to be fitted into corresponding dovetails formed for the purpose in one of said castings.

Secondly, that an oil holeis provided through a collar on the axle on the inner side of the wheel, while an oil-groove leads from said oilhole in said collar along the upper side of said axle and conveys the oil to and distributes it evenly within the bearings of the wheel. This oil-hole is covered by a box secured to the axle and provided with an easily-raised lid.

Thirdly, that a solid removable bush or sleeve is employed in combination with a 1101- low hub constructed substantially as herein before mentioned.

Fourthly, that the axle-cap is provided with a certain cam arrangement adapted to shoot a pair of outwardly-sliding bolts into a groove or other socket or sockets formed on the inside of the outer half of the hub, so that said cap will be secured thereby and will effectually be prevented from unscrewing, while it will prevent the usual nut upon the end of the axle from shaking off.

Referring to the accompanying drawings, Figure 1 is a vertical central longitudinal section of the hub and inner ends of the spokes of a wheel constructed according to my invention. Fig. 2 is a vertical transverse section on line a: ac, Fig. 1. Fig. 3 is a vertical transverse section on line 11y, Fig. 1. Fig. 4

is an elevation of the outside of the hub of my improved wheel. Figs. 5 and 6 are elevations, respectively, of the inner and outer sides of a screw-cap for carriage and other wheels constructed according to my invention. Figs. 7 and 8 are respectivelya side elevation and an end elevation of the removable bush or sleeve of my improved wheel, While Figs. 9 and 10 are respectively a side elevation and an end view of one of the spokes thereof.

The hub of my improved wheel consists of a pair of hollow castings A A preferably of malleable iron or steel, which are'preferably screwed the one to the other, as shown at a, Fig. 1. One of these two castings-say, for instance, the outer one A is provided with a number of dovetail grooves or sockets a a, adapted each to receive one of the correspondingly-shaped ends Z7 Z) of the spokes B, as clearly illustrated in Figs. 1 and 2. These two hollow castings A A are secured the one to the other by bolts 0, passing through holes (I, formed in the flanges D on their inner ends, as well as through holes cl, Figs. 1, 2, and 9, formed between each of the inner ends of the spokes B. An oil-hole E passes through the collar f on the axle F of the vehicle, and is provided with a cap 6, while a groove e is formed along the top of said axle and serves to convey the oil to thecenter of the wheel, thereby insuring a far better lubrication of said wheel, and at the same time preventing the entrance of grit or dirt.

The bushing of my improved wheel consists, simply, of a slightly-tapering sleeve or bush G, Figs. 1, 2, 3, '7, and S, driven into the center of the hub of the wheel, as shown in Fig. l, and prevented from turning therein by the projections or feathers g, engaging in grooves or recesses cut or otherwise formed in an inwardl y-projectin g annular web g, provided inside the hollow casting A.

The axle-cap II, Figs. 1, 4, 5, and G, is first screwed into and is then secured within the end of the hollow casting A by means of a pair of outwardly projecting bolts I I, which are connected by links j j to and are arranged to be forced outwardly by a suitablyshaped cam J, pivoted centrally within said 'cap and capable of being partially rotated by means of a saw cut or nick j, cut across the outer end of its spindle 9' These bolts I I when projected are adapted to engage in a circular groove '5 1', formed around the inside of the outer portion of the casting A, Whereby the cap H will be efiectually kept in its place in said casting, and will therefore prevent the usual nut K on the end of the axle from shaking off.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is- 1. In a vehicle-whee1,a hub composed of two sections adapted to be screwed together, one of said sections being provided with radial spoke-.rnortises, the diameter of which is eater at the inner than t the outer ei p v p I, t-ion with spokes having a correspondihgl shaped i n en wh reb a i terl e QQ iQ-ihi s arm d etw en h h h h rtiee ee' the epekesend belte stendi e h u heth seet'iehs and b tween the e jee t h end: Qt e s okes, where y the huh e ti e are mere fi mly el tog the an th spok s interleekedi substa ll s end f r e pu poses spe fied.
